BEDSIEAD-FASTENING.

Specification of Letters Patent No.

To all whom t may concern:

Be it known that I, JOHN MoULToN, of Ossipee,'in the county of Carrolland State of New Hampshire, have invented a new and useful or ImprovedBedstead-Fastening; and I do hereby declare that t-he same is fullydescribed and represented in the following specification andaccompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure 1, denotes a side view of the end of' abedstead rail having my improvement applied to it. Fig. 2, is a top viewof it. Fig. 3, is a view of the end of it. Fig. 4, is a view of thebedstead post, and shows the form of the front end or part of themortise or socket into which the tenon and fastening of the rail isinserted. Fig. 5, is a vertical section of the post, taken centrally andlongitudinally through the mortise. Fig. 6, is a similar verticalsection of the post and rail tted together. Fig. 7, is a horizontalsection of the same taken through the fastening bolt. Fig. 8, is a topview of the fastening bolt. Fig. 9, is a side view of it.

In the above drawings, A, represents the post, and B, the rail orportion of the rail of a bedstead.

C, is a tenon made on the end of the rail, the said tenon being placednearer to the under surface of the rail than it is to the upper surfaceof it, as seen in Figs. 1, and 3.

I), is a mortise cut or formed in the bed-` stead post, and for thereception of the said tenon; the said mortise being made of a verticaldepth somewhat greater than that of the tenon as shown in the drawings.rl`he horizontal widt-h of the mortise is constructed in accordance withthat of the tenon. The mortise is also constructed with either one ortwo horizontal lateral passages a, a, for the admission of the projections or parts of the fastening bolt which extend beyond the tenon oneither one or both sides of it as the case may be; the said lateralpassages being arranged as seen in the drawings. Out of and downwardfrom each lateral passage a, a, and in the sides of the mortise, aseries of vertical passages or recesses b, b, b, are cut, and so as toreceive the projections c, c, c, c, of the fastening bolt. The saidfastening bolt cons ists of a bolt or piece of metal made with angularprojections or teeth c, c, c, c, on either one or both sides of it asseen in Figs. 8, and 9, which projections when the bolt is inserted andfixed in the end of the bed- `from the vertical as seen in Fig. 1.

stead rail, project beyond either one or both of the sides ofthe tenonas seen in Figs. 2, and 3. These projections should be constructed insuch manner, that they may not stand exactly vertical but be a littleinclinpld T e object of such Inode of constructing them being, to causethem to draw or move the tenon longitudinally while it is being forceddown in a vertical direction and during its insertion and depression inthe mortise. The fastening bolt is made with a recess d, at or near itsrear end, through which recess when the bolt is inserted in the rail aniron pin is passed. lVhen driven through the side of the rail, and intothe bolt, the pin serves to keep the bolt in place; f

In order to connect t-he rail with the post, the tenon is inserted inthe mortise horizent-ally, and so as to permit the projections of thebolt to pass into the horizont-al spaces 0., a, until the shoulder e ofthe tenon is nearly or quite brought into contact with the side of thepost. This being effected the rail is next to be'pressed downward so asto cause the projections of the bolt to enter the vertical recesses b,b, b, Z9, and the bottom of the tenon to rest on that of the mortise.The rail and post will then be so confined together that they cannot beseparated unless the former is rst elevated so as to raise theprojections of the fastening bolt out of their recesses b, b, b, b.

The above fastening is a very simple and desirable one.

I deem it indispensable in the construction of my bedstead fasteningthat there shall be several at least three or four of the projections orflanges c, on each side of the tenon in order to take firm hold of thewood in the recesses b. I do not therefore claim the use of a singleflange, hook, or projection on the side of the tenon of a rail to lmysignature this twenty eighth day of April A. D. 184.9.
